MaskedTextBox Custom Rules

I'm looking to add custom rules to a masked textbox and there is not enough documentation or examples to explain how this works properly.

$(this).kendoMaskedTextBox({

mask: "mm/dd",

rules: {

mm: "any number between 01 - 12",

dd: "any number between 01 - 31"}})

I attempted to use a masked date picker, but it still allows for entries like "48/99" which is incorrect.

Is it possible to do something like this using custom rules and regex?

TreeView with remote hierarchical datasource

I have this datasource

var HDS = new kendo.data.HierarchicalDataSource({

error: raiseAjaxErrorWindow,

transport: {

read: {

url: HDS_URL,

dataType: "jsonp"

}

},

schema: {

model: {

id: "id",

hasChildren: "hasChildren",

data: "data"

}

});

and this tree view config

    $("#treeview").kendoTreeView({

        dataSource: HDS,

        dataTextField: "text",

        dragAndDrop: false,

        select: onSelect,

        expand: onExpand,

        collapse: onCollapse

    });

The HDS url delivers a callback that looks like

jQuery18209300398211926222_1361181052330(
[{"id":"2a1bfc85-06d5-4702-bc92-d659fcae9d39",
"text":"Group 1",
"hasChildren":"1",
"data":{"type":"1","depth":2,"color":"red","flavor":"up"}
}])

call this the foobar node.

How do I add extra rendering to the tree node to display the items in the data field?

When a node having children is opened, the HDS url is automatically ajaxed with data id=<id of node>.

Is there a way to configure the transport.read so that when it is to be opened, it will use some or all of the the extra data of the foobar node when ajaxing the url. ?

For instance, I would like the HDS to be called with the additional data depth=2&type=1

If so, where would I put this little magic ?

Thanks,
Richard

[Solved] plot lines or bands on scatter charts?

I would like to draw a line parallel to the X axis on a scatter chart at the average of the Y values. I see plot bands listed for other types of charts, but nothing for scatter charts. For run, I tried adding a plotBands config to the yAxis element of my scatterline chart, but nothing shows up.

Is there a plot line feature available for scatter charts?

I didn't see anything in the documentation:

Value Axis Label Formatting

Hello,

I have the value axis labels shown in the "current" screenshot. I'm hoping to format them as shown in the "desired" screenshot, ie. displaying "25000" as "$25k". I am able to add the "$" and "k" using valueAxis.labels.format. But I'm unable to perform math on the value itself or remove the last two zeros.

Any help is greatly appreciated.

Thanks!

Drag & drop support

I'm very excited to see the birth of this new component. Does the component support drag & drop. My use case would be to have a tilelayout dashboard area to which I would like to drag & drop new items from a side toolbar.

Looking at the reference, it doesn't seem that this component currently support dynamic changes (add/remove) at all. Is that right? And if so, is it on the roadmap?

Best regards,
Ron

Closing a Kendo Confirm Dialog

I have the following code to present a confirmation to the user but I am not sure how to close it ..

kendo.confirm("Are you sure that you want to Update the System Cache? (<strong>Recommended<strong>) </br></br> If Yes do not navigate away from this page")
.then(function () {
$('body').addClass('waiting');
$('html,body').css('cursor', 'wait');
$('btnUpdateCache').addClass('disabled');
kendoConsole.log("Updating cache data please wait");
kendoConsole.log("Do not navigate away from this page");
$('#console-log').show();
CLOSE IT HERE <<<<<
updateSystemCache();
}, function () {
//kendo.alert("You chose to Cancel action.");
});

Given that code how would I close it?

gantt data source filtered by date focuses on first interval date

Hi,

I implemented datasource filtering on my gantt (for jquery) widget which includes filtering of elements by start and end date. In terms of filtering logic, everything works fine, but this introduced interesting behaviour with my gantt. After any action (update of tasks via drag-n-drop for example), gantt is focused to the beginning of filter interval.

I did some debugging and I came to piece of code in kendo library (displayed below) which seems to be cause of the problem.

Is there any way to prevent this focusing, because it doesn't make much sense to scroll there if i change task somewhere in the middle of range.

Thank you

_render: function (tasks) {

var view = this.view();

var range = this._range(tasks);

var date = view.options.date;

this._tasks = tasks;

view.range(range);

view.renderLayout();

view.render(tasks);

if (date) {
